To all whom it may concern Be it known that 1, FRANK LODER, a cititowhich it appertains to make and use thel same.

This invention relates to the arttof resilient pneumatic tires and morespecilically to a particular form of outer casing comprising an innercasing of the composition of. cotton and asbestos having a leathercovering extending partially about the same, and provided with a treadsurface consisting of a plurality of layers of such materials as fabric,mineral wool, asbestos, and leather. Said tread surface is provided withnonskidding members secured between the outer layers of the treadsurface.

l1n practical fields the details of construction may be subjected toalterations, falling within the scope of what is claime.

The invention comprises further features and combination of parts, ashereinafter set forth, shown in the drawings and claimed.

1n the drawings :-F igure 1 isa sectional view through the improvedresilient pneuinatic tire constructed in accordance with the invention.F ig. 2 is a plan view of a section of the tire, showing the treadthereof and the non-skidding members. Fig. 3 is a view in side elevationof the tire construction on a wheel rim, showing parts of 'the tirebroken away and in section, so as to illustrate the vital .parts ofconstruction on the interior of the tire. Fig. 4: is a detail view inperspective of one of the steel suction non-skidding members. Fig. 5 isanother view of the member showing the opposite surface thereof to thatshown in Fig. 4.

Referring more particularly rto the drawings, 1 designates the casingofthe tire as a whole having a casing of any suitable material, such asa composition of cotton as shown. This casing 2 is provided with asuitable outside leather covering 3. The casing terminates in adjacentenlargements 4 having bores or hollow portions 5. These enlargements aredesigned to engage the' l usual elencher-fianges of the wheel rim, as

shown at 6. The .composition cotton cas- 1ng2 is provided with particlesof-jasbestos i.

Extending partially about the casing, that is,'as shown in cross sectionis a layer of l fabric, or a composition thereof and mineral 'wool 8,and over this layer is a layerof asbestos 9, which terminates atportions of thecasing as indicated at 10. Over the layer of the asbestoslining 9 is another layer of mineral wool 11, and adjacent this surfaceor lining is a leather covering 12, which merges into the leathercovering 3, as indi' cated at 13. The leather covering 12 is providedwith a series of openings 14:, through' which the flanges 15 of thesteel non-skidding members 16 extend. rl`he parts 17 or. plates fromwhich the non-skidding mem bers project are embedded between the leathercovering 12 and the mineral wool layer, as shown, and are riveted to theleather covering 12 by the flat rivets 18.`

-Rivets 19 also extend through the non-skidcing members and through theasbestos layer 9, thereby further securing the nonskidding members inplace. The flanges 15 of the non-skidding members are formedsubstantially of a diamond-shaped contour, and extending transversely ofthe non-skidding members are corrugatons 20.- The riveted ends of therivets 19 have elongated plates 21, upon the inner face of the asbestoslining or layer 9. Arranged annularly of an inner lining (which isdisposed adjacent the composition cotton casing) of any suitablematerial, is a multiplicity of pneumatic tubes 23, some of which areconstructed of a composition of cotton and asbestos fabric, in sucliwiseas to provide tubes of airproof character. Arranged between the tubes 23and the innermost lining 22-is a light asbestos packing 24:. It is to beremembered that the elasticity of the tube 23 is to be'substantially thesame as the usual pneumatic rubber tube, and yet of such character as tohold a larger and higher pressure of ain-*thereby enabling the tube tohave more stability and firmness. The tubes 23 may be either continuous,as Ashown in F ig. 3 having a division wall 26 and provided with aninlating check valve 27, or provided with t'wo ends arranged adjacenteach other as shown at 28 in Fig. 3, one end having an inlating checkvalve, and upon first inlating the tire the tubes 23 are first inflated,subsequently to which the key tube 29is inflated, thereby causing thevtubes 23 to crowd and compact closely together, but

not too much to prevent proper elasticity orv resiliency of the tire,yetsuflicient to render the tire stable and mobile.` ,T his innermost orkey tube 29 may be either continuous, or provided with two ends, in thevmanner si1nilar to the .tubes 23 and vsupplied with the usual in'latingcheck valve extension tube 30. Also, the innermost or key tube 29 may beconstructed of a composition of cotton and asbestos fabric, or a"composition of rubber, cotton and asbestos fabric, or of pure rubber, orleather as the case may require.

The tubes 23 are protected against puncturing owing to the improved ofthe treadof the outer casing, which tread,

as before stated, includesseveral layers ofV different materials ashereinbefore stated. The tubes are further protected, as Well as thetread, against puncturing, owingtothe provision 4of multiplicity of`suction nonskidding members, which tend-` to hold the tread proper fromcontact with the surface with which thel tire is designed `to engage.

From the foregoing it will be observed there has been devised a veryeiicient, simple and cheap construction of automobile wheel tires, andone which has been found exceedingly practical. The invention havingbeen set forth, what 1s claimed as new and ,useful is.:-

1. Improvements in an outer casing for a pneumatic tire comprising aninner casing -of a composition of cotton and asbestos, a

leather covering extendingabout the inner casing and terminating alittle beyond the center of the casing on each side, a tread surfacethereforl consisting ofv a composition of fabric and mineral wool andextending almost to the center of the casing yon each side thereof, alayer of asbestos covering the composition of fabric and mineral wooland terminating' substantially adjacent the Icen-` ter of the casing oneach side, a second layer of fabric andmineral wool adjacent ktheasbestos'layer and terminating at substantially the center of the casingon each side thereof,

construction structure of the tread surface, said second' leather layerhaving openings therein to receive rotectin non-skiddinv' members which.

are riveted to the asbestos layer and the slecond layer of fabric andmineral wool.

2. Improvements in an outer casing for a pneumatic tire comprising aninner casing of a composition of cotton and asbestos, a leather coveringextending about the inner casing and terminating` a little beyond thecenter of the casing on each side, a tread. surface therefor consistingof a composition of fabric and mineral wool and extending al most to thecenter of the casing on each side thereof, a 4layer of asbestos coveringthe composition of fabric and mineral wool and terminating substantiallyadjacent the center of the casing on each side, a second layer of fabricand mineral wool adjacent theasbestos layer and terminating atsubstantially the center of the casing on each side thereof, a secondlayer of leather adjacent the second layer of fabric and mineral wooland terminating adjacent the center of the casing on each side andmerging into the first leather layer, thereby entirely inclosing theinterior structure of the tread surface, non-skidding members interposedbetween the second leather layer and thesecond fabric and mineral woollayer and protruding through the second leather layer, and means forriveting the non-slriddingmembers to the asbestos layer and the secondfabric layer.

In testimony whereof l have signed my name to this specification in thepresence of two subscribing witnesses.
